This work presents a new technique based on ray tracing to extract and analyze scattering centers from complex targets, which is called ray clustering. The input of this method is the target CAD model and the output is the dominant scattering centers. This method can separate the echoes from different components by clustering rays owning the different paths and establish relationship between target...
This paper presents a forward approach to establish parametric scattering center models for known complex radar targets. In this approach, an automatic technique based on ray tracing and clustering is first developed to extract scattering centers directly from the computer-aided design (CAD) model of the targets. Following this, a set of forward methods is developed to determine the physically relevant...
Virtual Scene Technology is one of the important parts of VR systems. It takes charge of Vision issue in VR systems, and is the most important fact to affect the immersive of the system. There are many problems in training simulation of artillery reconnaissance radar, such as the battlefield environment isn't living, the load of assemble and disassemble is large, the training cost is high. The virtual...
